In 2013 the name 'George' became the 10th most popular name in Britain, according to USA Today, which was also the year the Duke and Duchess of Cambridge welcomed their son Prince George.

Similarly, when the pair welcomed their daughter Princess Charlotte in 2015, the name suddenly gained some traction and has stayed in the top 20 girls' names in the US for the last five years.

Currently, Charlotte sits at number five in the most popular girls' names for the midway point for this year, according to the data from Nameberry.

The youngest of the Cambridge children, Prince Louis, hasn't kicked off the same hype with his name, although it currently sits at 32 in the most popular boys' names, falling far behind his new cousin.
